3.5 GPIO
• ROM-ED92: GPIO1 (6 pins)
• GPIO_A_0: GPIO#549
• GPIO_A_1: GPIO#550
• GPIO_A_2: GPIO#551
• GPIO_A_3: GPIO#552
• GPIO_A_4: GPIO#553
• GPIO_A_6: GPIO#541
GPIO_A_0 and GPIO_A_1 Loopback Test
1. Connect the GPIO_A_0 and GPIO_A_1
2. Export the GPIO interface
# echo 549 > /sys/class/gpio/export
# echo 550 > /sys/class/gpio/export
3. Set the GPIO direction
# echo out > /sys/class/gpio/gpio350/direction
# echo in > /sys/class/gpio/gpio351/direction
4. Set output value and check
# cat /sys/class/gpio/gpio550/value
0
# echo 1 > /sys/class/gpio/gpio549/value
# cat /sys/class/gpio/gpio550/value
